                                             INC.

                                                               February 7, 2000
Dear Contract Owner:

   J. & W. Seligman & Co. Incorporated, Manager of Seligman Portfolios, Inc., is
pleased to provide the enclosed audited financial statements and accompanying
information for the fiscal year ended December 31, 1999. Performance and
portfolio commentary are also provided for each of the Portfolios.

   The 20th century ended on an extraordinarily optimistic note for the US stock
markets, with all major indices -- the Dow Jones Industrial Average, the S&P
500, and the NASDAQ -- at record highs. The broad-based S&P 500 had achieved a
fifth consecutive year of greater than 20% returns -- a record-breaking run.
Supporting these impressive markets was the US economic expansion -- now the
longest in US history. Throughout 1999, unemployment stood at a near 30-year
low, inflation remained tame, and consumer confidence soared. In addition, the
global economy rebounded strongly.

   By year-end, the US and global economies were stronger than perhaps anyone
had anticipated at the start of the year. Throughout 1999, the US economy showed
no signs of slowing, triggering concerns regarding inflation. In response, the
Federal Reserve Board has now increased the federal funds rate four times,
leaving this key rate 100 basis points higher than it had been at year-end 1998.
The Federal Reserve Board's skillful watch over the economy, both in its
response to the worldwide crisis of 1998 and its vigilance regarding inflation
in 1999, has been a key contributor to the long-term health of this remarkable
economy.

   While 1999 will certainly be remembered as a positive year for equity
investors, it was also a year of sharp contrasts. Despite stellar performances
by the popular indices, the market was extraordinarily narrow. Just over half
the stocks in the S&P 500 had positive returns. The outsized returns of a few
stocks also skewed the indices. Just seven stocks were responsible for half of
the S&P 500's return; five of these were technology companies, with four of
those delivering astounding triple-digit returns. Large-cap growth and
technology companies continued to dominate, while value stocks lagged
considerably. However, the market did show signs of a broadening trend, which we
believe will continue; 1999 was the first year since 1994 that small- and
mid-cap stocks delivered returns approaching those of large-caps.

   The markets also experienced a dramatic divergence between stocks and bonds.
The bond markets experienced one of the worst years on record, and 30-year US
government bond yields soared from 5.08% at the beginning of the year to 6.48%
by the end of the year. Unfazed, the stock market hit several new highs. We
believe this sharp divergence cannot continue; our view is that interest rates
will stabilize and equity price increases will be more modest.

   The past fiscal year was also characterized by significant divergence in the
performances of international stock markets. Although the economic background
was positive, increases in both short- and long-term interest rates around the
world placed a drag on stock market performance. In general, markets in Europe
rose modestly in US dollar terms, while stock markets in Asia -- including Japan
- -- rose sharply as evidence mounted that the regional economic recovery was
sustainable.

   Thank you for your continued support of Seligman Portfolios, Inc. We look
forward to continuing to serve your investment needs in the year 2000.

                                             Respectfully,

                                             /s/ William Morris
                                             William C. Morris
                                             Chairman
                                             J. & W. Seligman & Co. Incorporated

</TABLE>

     Nineteen ninety-nine was a difficult year for fixed-income securities.
During this time, the Federal Reserve Board increased the federal funds rate
three times, for a total of 75 additional basis points, while the US economy
continued to grow at a robust pace. These factors caused 30-year Treasury bond
yields to increase by 140 basis points, from 5.08% on December 31, 1998, to
6.48% on December 31, 1999.

     In the second half of the fiscal year, we sold some intermediate-term bonds
in favor of shorter-term securities in response to the generally negative
operating environment for bonds. This defensive strategy benefited the
Portfolio's performance during the second half of the year.

     We remained committed to pursuing favorable yield spreads, while at the
same time maintaining a high-quality portfolio. The average quality of the
Portfolio remained stable at AA. At year-end 1999, the Portfolio was 18%
invested in Treasuries, 5% in US government agency bonds, 13% in mortgage
pass-through securities, 3% in asset-backed securities, and 61% in corporate
bonds. During the year, the spread between Treasuries and corporates widened,
and we increased the Portfolio's exposure to corporates to pursue additional
yield. Over the course of the year, the Portfolio's yield increased from 5.61%
to 7.05%.

     We believe that 2000 will provide a more positive environment for bonds
then did 1999. Yields are likely to stabilize, which should allow for positive
total returns. While the Federal Reserve Board is likely to remain cautious
regarding any inflationary pressures, we believe it will not be as aggressive as
it was in 1999.

</TABLE>

     During 1999, growth stocks of all sizes generally delivered extraordinary
returns, while value stocks of all sizes generally lagged. A continued strong US
economy and improving worldwide economies, combined with low inflation, provided
a positive environment for growth stocks. Within the growth-stock universe,
technology -- driven by increased Internet demand and an explosion in wireless
communications -- was by far the best performing.

     The growth stocks in the Portfolio were strong performers within this
supportive environment, with the technology industry the single most positive
influence on performance during the fiscal year.

Seligman Capital Portfolio (continued)

Despite the fact that the Portfolio was  underweighted in the sector during the
period, the technology stocks it held delivered exceptional returns.

     In the fiscal year, the Portfolio purchased several what we believe are
"best-of-class" Internet companies that focus on the business-to-business
applications that allow companies to reduce expenses and increase sales. We
believe that such companies, which contribute to increased efficiency in the
rest of the economy, will continue to have opportunities for growth for years to
come. The Portfolio had relatively low exposure to health care because we
believed that the group had become overvalued following a very strong 1998, and
there were uncertainties regarding pricing pressure due to potential changes in
Medicare drug benefits. This low exposure benefited overall performance since
this sector was a poor performer for the year.

     Going forward, greater emphasis is likely to be placed on technology. In
particular, we will look for companies that use information technology to
increase sales and data warehousing, and for companies that are developing
innovative or improved products, especially in telecommunications. Within
technology, we anticipate remaining underweighted in hardware stocks and will
focus on software stocks, particularly those involved in business-to-business
e-commerce. We will also look for opportunities to gain more exposure to
wireless application protocol, which allows Internet access without a personal
computer (PC).

     We believe that a favorable climate for continued global growth lies ahead,
based on several factors, including the broader acceptance of the euro, reduced
barriers to trade, and Japan's economic progress and financial reforms. This
environment would likely benefit mid-cap companies with export-driven revenues.
We will seek to gain additional exposure to stocks that are positioned to
benefit from the recoveries abroad, particularly in Japan.

     Seligman Common Stock Portfolio pursues companies with attractive yields,
stable earnings growth, strong fundamentals, and reasonable valuations. In 1999,
this strategy was out of favor, and investors seemed willing to pay any price
for stocks that had been on an upward trend, with little or no regard for
valuations and fundamentals. However, we believe that remaining true to our
discipline, and avoiding stocks whose valuations seem excessive, will best serve
the Portfolio's shareholders over the long term.

     Steadily rising yields over the course of the year had a negative effect on
interest-rate sensitive sectors, such as the financial sector -- one of the
Portfolio's most heavily weighted industries. The strongest area of the
portfolio -- as for the market -- was technology. While the Portfolio was
underweighted in technology, the sector was such a strong performer that it was
the single largest contributor to overall portfolio returns. However, the
Portfolio's underweighting in technology hurt performance relative to the
broader market.

     The Portfolio benefited from its exposure to both basic materials and
capital goods, which were both strong market performers during the year. Health
care was one of the worst-performing market sectors because of uncertainty
regarding potential Medicare price controls for drug companies. The Portfolio
was about market-weighted in this sector, so our exposure to this sector didn't
hurt relative performance, but did negatively impact absolute returns. Consumer
staples also performed poorly as investors focused on these companies' lack of
pricing flexibility.

     We are cautiously optimistic regarding the outlook for value stocks and for
the Portfolio in the year 2000. We do not believe that the type of market that
prevailed in 1999-- one in which economic and company-specific fundamentals were
largely ignored-- can continue. Many good companies languished in 1999 and are
now trading at what we believe are exceptionally attractive prices. It is our
conviction that, ultimately, companies that are more attractively priced within
their industry groups will be recognized by the market.

     Technology is playing an ever-increasing role in the economy and in the
stock market, and in 1999 the industry was by far the best-performing market
sector. Technology's importance received public attention when, in November, the
Dow Jones Industrial Average, the most widely watched stock-market index, shed
four old economy stocks to make room for four new economy stocks. Three of these
four stocks -- Intel, Microsoft, and SBC Communications -- are technology
stocks.

     We were pleased with the perform ances of a number of the Portfolio's
holdings during 1999. Among the sectors that performed well for the Portfolio
were semiconductors and semiconductor equipment, satellites, computer hardware,
contract manufacturing, radio, and security software. The networking and
telecommunications equipment sectors of the portfolio performed extremely well;
however, the Portfolio's underweighting in these sectors hurt relative
performance. The Portfolio's holdings in computer-aided design software
performed poorly over the course of the year due to continued weakness in Asia
and a leveling off in demand in the United States.

     While industry fundamentals are outstanding, valuations are extremely high
by historical standards. Hence, we have become more vigilant in evaluating the
risk of the companies held by the Portfolio, and we have begun to pare back or
eliminate some of the most expensive securities.

     In spite of high valuations in many technology stocks, we continue to find
attractive values, particularly in the semiconductor and software sectors.
Within the high-growth Internet sector, we anticipate finding the most
attractive opportunities in business-to-business Internet. We don't expect to
find as many suitable investments in business-to-consumer, but believe that
there will be selective opportunities in this area. We also believe that, as the
Internet grows in acceptance and usage worldwide, companies that supply the
software and equipment that support this growth will continue to benefit. In
general, technology companies are truly changing global business. We believe
that the world is only in the early stages of technological expansion, and that
the sector will thus continue to offer enormous opportunities for long-term
investors.

     In 1999, small-capitalization stocks began to deliver returns that were
competitive with large-company stocks. However, last year's markets were
extraordinarily narrow, regardless of market capitalization. Growth stocks, and
particularly technology stocks, outpaced the rest of the market by a wide
margin.

     In the small-cap market, the stocks of companies with little or no earnings
outperformed for the year. These stocks are typically part of the new economy,
such as technology and communications, rather than the old economy, such as
energy and transportation. During fiscal-year 1999,

Seligman Frontier Portfolio (continued)

Seligman Frontier Portfolio pursued "middle-of-the-road" stocks in industries
such as software, semiconductors, and semiconductor capital equipment. These
companies play a vital role in the new economy, yet they are also money-making
enterprises.

     During the fiscal year, the technology sector was the Portfolio's
best-performing sector and the Portfolio's weighting in this area increased as a
result. The Portfolio remains underweighted in the Internet, however, since many
of these companies do not yet have any earnings, and the fundamentals underlying
these companies are typically weak. Despite high valuations and weak
fundamentals, the Internet was the best-performing sector of the small-cap
market. At the beginning of the year, the Portfolio suffered as a result of poor
stock selection in the health care sector, but most of the resulting drag on
performance was recovered by year end.

     We are optimistic for the Portfolio as we look into the year 2000. Smaller
companies, which many believed were at an increased risk for Year 2000 computer
problems, entered the millennium unscathed, and many small companies have been
delivering strong earnings reports that are meeting or beating the market's
expectations. We believe that the interest-rate environment will stabilize in
2000, which would be positive for the stock market as a whole and for
small-capitalization stocks. Finally, small-cap stocks continue to be priced
considerably lower than their large-cap counterparts, despite the fact that
smaller companies continue to have higher growth rates.

</TABLE>

     The past year witnessed a significant turnaround for global economies and
stock markets. In the wake of the financial crisis emanating from Asia in 1998,
major central banks around the world lowered interest rates and provided
liquidity. In response, the world economy enjoyed a sharp recovery and stock
markets, particularly in Asia, rallied strongly.

     As markets recovered, the Portfolio's relative performance was influenced
positively by three major factors. First, the Portfolio's overweighting in
technology and telecommunications was beneficial since these sectors performed
well. Increasing use of mobile communication devices, the Internet, and data
transfer boosted demand for computers, software, and connectivity. Second, the
Portfolio's concentration in Japanese emerging growth companies was beneficial
since these companies more than doubled in value during the year. Third, the
Portfolio's limited exposure to health care helped overall performance as the
sector lagged the broader market averages.

     The Portfolio remained broadly invested in three major growth themes:
Quality of Life, Productivity, and Consumption. During the year, we
significantly increased exposure to the Productivity theme, which includes
information technology and telecommunication services. At the same time, we
reduced exposure to the Consumption and Quality of Life themes.

     The Productivity theme provided much of the Portfolio's activity during the
fiscal year. We continued to add substantially to the Telecomms sub-theme, as
the increase in voice and data traffic over growing numbers of networks showed
no sign of abating. In fact, the provision of ever greater bandwidth promises to
accelerate. Telecomms now exceeds both Technology and Consumer Staples as the
biggest sub-theme, with about 16% of the Portfolio's assets invested in this
area.

     Among the Portfolio's thematic investments, the emphasis on technology and
telecommunications sub-themes is the most important. We believe that despite
near-term volatility, secular forces remain supportive of these sectors. The
transformation to a wired world has only just begun, with the most momentous
changes yet to come. Overall, in an environment of low inflation and intense
competition, real growth will continue to be scarce. The experience of recent
years has shown that investors around the world are eager to invest in
businesses that promise high profit growth, and we believe this situation will
continue.

     Looking ahead, news about global economic activity is likely to remain
positive. As a result, interest rates are expected to move higher, first in the
US and Europe, and eventually in Asia. However, much of this increase has
already been anticipated by market participants, and as long as cyclical
inflationary pressures remain muted, investors are unlikely to be overly
concerned about higher interest rates. We expect that, as tighter monetary
policy preempts higher inflation, long bond yields in most markets will begin to
decline. Such an outcome would be supportive of global growth stocks.

     During fiscal year 1999, performance for global smaller companies was
generally volatile, and returns among sectors and regions showed great
disparities. Improving world economic growth should have provided a positive
background for smaller companies. However, with the exception of a few specific
sectors, smaller companies overall have lacked pricing power.

     In the US, small-capitalization stocks began to deliver returns that were
competitive with large-company stocks. However, last year's markets were
extraordinarily narrow, regardless of market capitalization. US growth stocks,
and particularly technology stocks, outpaced the rest of the market by a wide
margin. In the fiscal year, the technology sector was the Portfolio's
best-performing US sector and the Portfolio's weighting in this area increased
as a result. The Portfolio remains underweighted in the Internet, however, since
many of these companies do not yet have any earnings, and the fundamentals
underlying these companies are typically weak. Despite high valuations and weak
fundamentals, the Internet was the best-performing sector of the US small-cap
market.

     In the UK, smaller companies enjoyed strong performance relative to larger
companies. During the first six months of the year, in particular, smaller
companies performed very well. More recently, interest-rate increases slowed
this outperformance, but smaller companies ended the year strongly. The
Portfolio remained consistently overweighted in the United Kingdom. The
allocation to the UK was 17.8% in January, rose to a peak of 19.9% in October,
and fell to 16.7% by year end. In the UK, we emphasized service companies and
technology, which benefited performance since these companies have performed
very well.

     Smaller companies in Continental Europe remained generally out of favor for
most of the period. Merger and acquisition activity was concentrated among large
companies, and the portfolio restructuring that followed European Monetary Union
also favored larger companies. These more than offset the positive earnings
growth prospects for smaller companies. The Portfolio was generally neutral to
slightly overweighted in Continental Europe during the period. However,
valuations are now quite low and we are looking for an opportunity to increase
this weighting.

     In Japan, smaller companies participated in the rising stock market, but
generally lagged behind larger-company stocks. The strengthening of the yen
during the fiscal year boosted returns for US investors. Within smaller
companies, those companies and sectors with visible growth prospects delivered
exceptional performance. We believe the Portfolio has very good exposure to
fast-growing companies, some of which delivered strong performance during the
year. The Portfolio's allocation to Japan more than doubled over the year.
However, valuations for high-growth companies are now quite high and we do not
anticipate further increasing the Portfolio's Japanese weighting.

     In the Pacific, smaller companies generally performed in line with those of
larger companies and, as a result, rose strongly during the year. The Portfolio
moved to a significant overweight position during the course of the year,
doubling its allocation from 2.9% in January to 5.9% at the end of the year. The
Portfolio focused on companies in the technology and service-related areas,
which have generally performed very well. We anticipate remaining overweighted
in the Pacific, and may in fact further increase exposure to this region.

     Technology stocks enjoyed an exceptionally strong year, outperforming the
broad market by a wide margin. Every region of the global stock market saw the
same pattern with investors becoming increasingly disenchanted with the low
levels of growth offered by traditional companies and increasingly enthusiastic
about the apparently open-ended growth opportunity provided by the technology
industry.

     Although the fiscal year began with some apprehension about the impact of
Y2K on technology spending patterns, demand remained strong across the board.
The growth of the Internet and its increased use by both businesses and
consumers remained the most significant driver of technology spending. While the
US originally led this trend, both Europe and Asia are catching up rapidly.
Growth of the Internet has had positive implications for spending in areas such
as storage, servers, communications equipment, and particular segments of the
software and services markets. Wireless demand has continued unabated and, with
the general pick-up in global economic activity, demand has increased sharply
for components. Relatively few areas of the industry have lagged behind, but the
key difference in the performance of technology stocks this year has been their
positioning vis-a-vis the Internet.

     We maintained a significant weighting in the US throughout the year while
adding to the Portfolio's position in Japan during the spring. We continued to
make major commitments to both the communications and semiconductor sectors, and
enjoyed a strong year in both areas. During the period, we reduced the
Portfolio's exposure to the personal computer and software/services markets.

     As we enter the Year 2000, the technology industry's fundamental outlook
remains positive. We expect earnings growth to accelerate, which should help to
support what are admittedly fairly high valuations. The latter, together with
the extent to which stock market performance has been polarized over the last
year, create the conditions in which there is some risk of a switch back into
value and cyclicals. However, we believe that the technology industry remains
well positioned for long-term growth.

     All fixed-income securities, including those held by the Portfolio, faced
the formidable headwind of rising interest rates during the past fiscal year.
This difficult operating environment was the single biggest factor affecting
Portfolio performance during this time. The high-yield market, while
withstanding interest-rate increases better than many other fixed-income
securities, experienced some ad verse market conditions unique to high-yield
bonds. Since the 1998 global financial crisis, the high-yield market has
suffered from reduced liquidity. This has widened the yield spread between
high-yield bonds and Treasuries with similar maturities. In addition, during
1999, new supply of high-yield bonds outpaced demand significantly. This
imbalance drove prices for existing high-yield issues lower.

     During the past fiscal year, we began to seek more opportunities in the
high-growth areas of technology, wireless communications, and telecommunications
infrastructure companies. In particular, we are optimistic about communications
tower companies, fiber

optic cable companies, Internet companies, and European telecom companies.
During the next three years, the growth rate for fiber cable deployment and
bandwidth demand is expected to grow by 30% per year. This increase in demand is
being driven by the growing use of the Internet. We believe the Portfolio is
currently well positioned to capitalize on the increasing demand for data,
video, and telephony services.

     During the period under review, we reduced the Portfolio's exposure to
health care, since this sector continues to struggle because of changes in
Medicare reimbursement programs. We also reduced the Portfolio's exposure to
economically sensitive sectors since these areas are more at risk if interest
rates head higher.

     We believe that the outlook for the high-yield market and for the Portfolio
is positive. The interest-rate environment during was extraordinarily
unfavorable for fixed-income securities, and we do not believe that this will
continue in 2000. As interest rates stabilize and global economies continue to
recover, we believe that the prices for high-yield bonds in general will begin
to move higher. We are particularly optimistic regarding the prospects for the
securities in the Portfolio. Throughout 2000, we expect to continue to seek
opportunities in the high-growth areas of wireless communications,
telecommunications infrastructure, Internet, cable, and media-related sectors.

     Seligman Income Portfolio had a difficult 1999 as a result of a narrow
stock market that overwhelmingly favored growth stocks over value stocks, and a
fixed-income market that was dragged lower because of steadily rising interest
rates.

     During the past fiscal year, we significantly reduced the Portfolio's
exposure to fixed-income securities, while we increased the Portfolio's exposure
to the stock market. We believe that this heavier stock weighting will provide
the Portfolio with more opportunities for capital appreciation. At the same
time, by continuing to maintain a substantial exposure to investment-grade
corporate bonds and government bonds, we hope to cushion the Portfolio from the
historically higher volatility of the stock market.

     We are cautiously optimistic regarding the outlook for the stock market and
the fixed-income market for the year 2000. We believe that the stock market will
broaden considerably from what we experienced in 1999, and that value stocks
will be rewarded. In addition, we believe that yields will stabilize, allowing
fixed-income securities to post positive total returns.

     The past fiscal year was characterized by significant divergence in
regional stock market performance. The UK stock market generally tracked the ups
and downs of the US market. However, there was significant movement within the
stock market as a whole. As the UK economic recovery seemed well underway, more
domestic and economically-sensitive stocks performed well. However, there was an
abrupt change in July when the Bank of England raised interest rates, and these
stocks sold off sharply. Throughout the period, stocks in technology and
telecommunications performed well. Our weighting in the UK remained relatively
stable over the course of the year. We were overweighted in UK economically
sensitive stocks for most of the year, which benefited the Portfolio. However,
following the interest rate increases, we have moved to a more neutral position
in these stocks.

     In local currency terms, Continental European stock markets performed well.
However, because of the weakness of the euro, US dollar returns have been more
subdued. Economically-sensitive stocks generally performed well while defensive
stocks underperformed. In addition, telecommunications and technology performed
well throughout the year and, unlike in the UK, this trend has continued. A high
level of merger and acquisition activity also benefited the UK markets, and this
is likely to continue. The Portfolio remained overweighted in Continental Europe
throughout the year, which has placed a drag on performance. However, our move
out of defensive stocks early in the year was beneficial. Now that the economic
recovery has broadened throughout Europe, we will remain overweighted in
Continental Europe since we anticipate strong corporate profit growth in year
2000 with ongoing restructuring activity.

     The Japanese stock market was the best performer last year, boosted by a
strong rise in the yen versus the dollar. The big turnaround came towards the
end of the first quarter when the first signs of economic recovery emerged. In
particular, the stock market was boosted by major inflows of overseas money. The
strong yen, however, damaged profits in the export sector. Investors have
focused on what could be described as "new Japan" stocks, mainly in the service
and technology sectors. The Portfolio was initially underweighted in Japan, but
increased this weighting significantly during the year, particularly in early
March.

     In the Pacific, the strongest recoveries have been Korea and Singapore. In
contrast, continued political turmoil in Indonesia placed a drag on stock market
performance. The Portfolio remained underweighted in the region, which was a
negative given the strong recovery. Overall, improving economic growth on a
global basis should be positive for the pacific region and we will seek
opportunities to increase the Portfolio's exposure during the coming fiscal
year.

     Emerging markets benefited from improving global growth and performed well
during the year. Foreign investors once again sought opportunities in these
markets, as the fears of last year subsided. The Portfolio reduced its emerging
market exposure during the period, but had significant holdings in Greece, which
performed exceptionally well. In Latin America, the Portfolio was concentrated
in Mexico and Brazil.

     The economic outlook for emerging markets is as good as it has been for
some time, with steady growth and low inflation likely to continue. However,
central banks are now more concerned regarding inflation, and interest rates may
rise slightly from current levels. For the first time in some time, earnings
growth outside the US may be higher and international stock markets are now
beginning to perform much better following their long period of underperformance
against US markets.

     The Portfolio benefited during the first eight months of its operations by
a very favorable environment for growth stocks. Technology stocks, in
particular, enjoyed exceptionally positive performance. Despite the fact that
the Portfolio was underweighted in this industry, the technology stocks in the
Portfolio delivered very strong results and the sector made a positive impact on
overall performance. The Portfolio was underweighted in health care during this
time, which benefited overall performance since this sector was a poor
performer.

     Since the Portfolio's inception, we have pursued large-capitalization
companies, with particular emphasis on those with longer-term track records. In
general, we are attracted to stocks with strong price-to-earnings growth rates
looking two years ahead.

     We believe that the Portfolio is well positioned as we head into the new
year. We anticipate increasing the Portfolio's technology weighting during the
coming fiscal year, and believe that this industry will continue to be a
high-growth area and a strong market performer. We plan to seek additional
opportunities in companies that are positioned to benefit from the recoveries
abroad, particularly in Japan.

During the past fiscal year, the outsized performance of a small number of
stocks within the S&P 500 carried the performance of the entire Index for the
year. The stocks that did well were primarily large-capitalization growth and
technology stocks. Seligman Large-Cap Value Portfolio had, and continues to
have, very low exposure to the technology industry because we believe that the
vast majority of these stocks do not represent good value. Stock prices for
these companies continued to rise over the course of the year, despite often
poor underlying fundamentals, including a consistent lack of earnings for many
of these companies, and a continued rise in interest rates.

     Last year's market was, to a great extent, driven by momentum; a small
number of stocks were being bought simply because their prices appeared to be on
an upward trend. The rest of the market, and with it many attractively valued
stocks, lagged behind. Despite the seemingly robust performance of the S&P 500,
nearly half of the stocks in the Index posted negative returns for the year,
with value-style stocks trailing growth-style stocks to an unprecedented degree.

     In the period under review, some of the Portfolio's individual stock
holdings delivered poor results. These stocks, which were within the aerospace,
office equipment, food, and packaging sectors, declined because of lower
earnings expectations. In all these cases, we reduced, or completely eliminated,
the Portfolio's exposure to these companies over the course of the fiscal year.

Seligman Large-Cap Value Portfolio (continued)

     Despite a difficult 1999, we continue to favor the financial sector since
we think that many of these companies remain good values, and we forecast a
better operating environment for this industry in the year 2000. We believe that
interest rates, whose upward trend was so detrimental to these stocks in 1999,
will stabilize.

     During fiscal year 1999, we eliminated or reduced some positions that had
done well either because we did not believe they continued to represent good
value or because they had increased to a degree that they represented too large
a percentage of the portfolio. We continually monitor the Portfolio to ensure
that no single holding is excessively overweighted and that the Portfolio
remains well diversified.

     We believe that value stocks will be recognized by the market in 2000, and
believe that the overall economic environment bodes well for value stocks. We
forecast a slowing US economy, but a strengthening international economy. Value
companies tend to be economically sensitive and thus perform well within a
growing global economy. In addition, a more sedate US economy may allow interest
rates to decline, which would further benefit value stocks -- particularly
financial stocks -- since they tend to do well when interest rates fall.

</TABLE>

  Seligman Small-Cap Value Portfolio was negatively impacted by last year's
market environment, which overwhelmingly favored growth stocks over value
stocks. Last year's market largely ignored fundamentals and was one of the most
narrow on record. A small number of stocks, particularly in the technology
sector, continued to experience price gains, while much of the market lagged
behind. The Portfolio has very low exposure to technology because the vast
majority of these stocks do not fit our value criteria. Stock prices for these
companies continued to rise over the course of the year, despite often poor
underlying fundamentals, including a consistent lack of earnings for many of
these companies, and a continued rise in interest rates.

     During 1999, many companies within the Portfolio posted strong operating
results, but this was not reflected in higher stock prices. One of the
Portfolio's long-term holdings in specialty retail delivered poor stock-price
performance during the period despite posting better-than-expected operating
performance. This is a specific example of the market's lack of regard for
fundamentals during this time. We continued to hold the stock because we believe
that if a company continues to deliver strong results, the market will
ultimately recognize the stock.

     The energy sector as a whole outperformed during the period. The
Portfolio's overweighting in the sector, as well as the strong performances of
individual energy stocks in the Portfolio, helped both absolute and relative
performance. Financial stocks came under considerable pressure as a result of
rising interest rates. These companies are among the most sensitive to
interest-rate changes; they tend to perform poorly when interest rates go up,
and perform well when interest rates decline. While the Portfolio did have
significant exposure to financial stocks, the Portfolio was, fortunately,
considerably underweighted in this sector versus its benchmark, the Russell 2000
Value Index.

     We are optimistic regarding the prospects for small-company value stocks
during the coming fiscal year. We are convinced that it is only a matter of time
before investors begin to pursue these relative bargains in the midst of a
broader market that in some areas has become remarkably expensive. The Russell
2000 Value Index now has a dividend yield higher than that of the S&P 500. This
is unprecedented. Small companies typically have higher earnings growth rates,
but lower dividend yields. Currently, small companies are offering higher
current yields in addition to higher growth rates. We believe that these strong
underlying fundamentals, in addition to attractive valuations, will ultimately
be recognized by the market.

+ Investments in mortgage-backed and asset-backed securities are subject to
  principal paydowns. As a result of prepayments from refinancing or
  satisfaction of the underlying instruments, the average life may be less than
  the original maturity. This in turn may impact the ultimate yield realized
  from these investments.

Annuity Account 2 ("CLNYVA-2"), which has been offered by Canada Life Insurance
Company of New York ("CLNY"), and Canada Life of America Annuity Account 3
("CLVA-3"), which has been offered by CLICA. CLVA-2 and CLNYVA-2 are registered
as unit investment trusts under the Investment Company Act of 1940, as amended
(the "1940 Act") and fund variable annuity contracts (the "CLVA-2 Contracts")
issued by CLICA and CLNY. CLVA-3 is not registered or regulated as a unit
investment trust under the 1940 Act in reliance on the exemption provided in
Section 3(c)(11) of the 1940 Act, and funds variable annuity contracts (the
"CLVA-3 Contracts") issued by CLICA. Effective January 1, 2000, CLICA and CLNY,
as the case may be, stopped offering new CLVA-2, CLNYVA-2 and CLVA-3 Contracts.
However, existing Contract holders will be able to continue to acquire shares of
the Fund. Additionally, on and after January 1, 2000, shares of the Fund will
continue to be provided as the investment medium for other variable annuity
separate accounts established and offered by CLICA or its affiliates ("Canada
Life Separate Accounts") and will be offered as the investment medium for
variable annuity separate accounts established and offered by other insurance
companies not affiliated with CLICA. Prior to June 30, 1999, shares of Bond,
Capital, Cash Management, Common Stock, and Income Portfolios were provided as
the investment medium for Seligman Mutual Benefit Plan (the "Mutual Benefit
Plan"), a separate account of MBL Life Assurance Corporation ("MBL Life").

2. Significant Accounting Policies -- The financial statements have been
prepared in conformity with generally accepted accounting principles which
require management to make certain estimates and assumptions at the date of the
financial statements. The following summarizes the significant accounting
policies of the Fund:

   a. Security Valuation --Investments in US Government and Government Agency
   securities, bonds, convertible securities, and stocks are valued at the most
   current market values or, in their absence, at fair market values determined
   in accordance with procedures approved by the Board of Directors. Securities
   traded on an exchange are valued at the last sales price or, in its absence
   and in the case of over-the-counter securities, at the mean of closing bid
   and asked prices. Short-term holdings maturing in 60 days or less are valued
   at amortized cost. Investments held by Cash Management Portfolio are
   generally valued using the amortized cost method which approximates fair
   value. Investments of certain other funds in the Seligman Group of Investment
   Companies purchased to offset the Cash Management Portfolio's liability for
   deferred directors' fees are valued at current market values. b. Foreign
   Securities -- The Portfolios may invest up to 10% of their total assets in
   foreign securities (except Global Growth Portfolio, Global Smaller Companies
   Portfolio, Global Technology Portfolio, and International Growth Portfolio,
   (together, the "Seligman International Portfolios"), which may invest up to
   100% of their total assets in foreign securities). Investments in foreign
   securities will usually be denominated in foreign currencies, and the
   Portfolios may temporarily hold funds in foreign currencies. The Portfolios
   may also invest in US dollar-denominated American Depositary Receipts
   ("ADRs"), American Depositary Shares ("ADSs"), European Depositary Receipts
   ("EDRs"), Global Depositary Receipts ("GDRs"), and Global Depositary Shares
   ("GDSs"). ADRs and ADSs are issued by domestic banks or trust companies and
   evidence ownership of securities issued by foreign corporations. ADRs and
   ADSs are traded on United States exchanges or over-the-counter and are not
   included in the 10% limitation. EDRs, GDRs, and GDSs are receipts similar to
   ADRs and ADSs and are typically issued by foreign banks or trust companies
   and traded in Europe. The books and records of the Portfolios are maintained
   in US dollars. Foreign currency amounts are translated into US dollars on the
   following basis:

     (i)  market value of investment securities, other assets, and liabilities,
          at the daily rate of exchange as reported by a pricing service;

     (ii) purchases and sales of investment securities, income, and expenses, at
          the rate of exchange prevailing on the respective dates of such
          transactions.

      The net asset values per share of Portfolios which invest in securities
   denominated in foreign currencies will be affected by changes in currency
   exchange rates. Changes in foreign currency exchange rates may also affect
   the value of dividends and interest earned, gains and losses realized on
   sales of securities, and net investment income and gains, if any, to be dis-

                                   -- P-64 --

                            Seligman Portfolios, Inc.

- -------------------------------------------------------------------------------

- -------------------------------------------------------------------------------

   tributed to shareholders of the Portfolios. The rate of exchange between
   the US dollar and other currencies is determined by the forces of supply and
   demand in the foreign exchange markets.

      Net realized foreign exchange gains or losses arise from sales of
   portfolio securities, sales and maturities of short-term securities, sales of
   foreign currencies, currency gains or losses realized between the trade and
   settlement dates on securities transactions, and from the difference between
   the amounts of dividends, interest and foreign withholding taxes recorded on
   the Portfolios' books, and the US dollar equivalent of the amounts actually
   received or paid. Net unrealized foreign exchange gains and losses arise from
   changes in the value of portfolio securities and other foreign currency
   denominated assets and liabilities at period end, resulting from changes in
   exchange rates.

      The Portfolios separate that portion of the results of operations
   resulting from changes in the foreign exchange rates from the fluctuations
   arising from changes in the market prices of securities held in the
   portfolios. Similarly, the Portfolios separate the effect of changes in
   foreign exchange rates from the fluctuations arising from changes in the
   market prices of portfolio securities sold during the period.

   c. Forward Currency Contracts -- The Seligman International Portfolios may
   enter into forward currency contracts in order to hedge their exposure to
   changes in foreign currency exchange rates on their foreign portfolio
   holdings, or other amounts receivable or payable in foreign currency. A
   forward contract is a commitment to purchase or sell a foreign currency at a
   future date at a negotiated forward rate. Certain risks may arise upon
   entering into these contracts from the potential inability of counterparties
   to meet the terms of their contracts. The contracts are valued daily at
   current exchange rates and any unrealized gain or loss is included in net
   unrealized appreciation or depreciation on translation of assets and
   liabilities denominated in foreign currencies and forward currency contracts.
   The gain or loss, if any, arising from the difference between the settlement
   value of the forward contract and the closing of such contract, is included
   in net realized gain or loss from foreign currency transactions. For federal
   income tax purposes, certain open forward currency contracts are treated as
   sold during the fiscal year and any gains or losses are recognized
   immediately. As a result, the amount of income distributable to shareholders
   may vary from the amount recognized for financial statement purposes.

   d. Federal Taxes -- The Portfolios' policy is to comply with the requirements
   of the Internal Revenue Code applicable to Regulated Investment Companies and
   to distribute substantially all of their taxable net income and net gain
   realized to shareholders. Therefore, no provisions for Federal income or
   excise taxes are required.

   e. Security Transactions and Related Investment Income --Investment
   transactions are recorded on trade dates. Interest income is recorded on the
   accrual basis. The Portfolios amortize market discounts and premiums on
   purchases of portfolio securities. Dividends receivable and payable are
   recorded on ex-dividend dates, except that certain dividends from foreign
   securities where the ex-dividend dates may have passed are recorded as soon
   as the Fund is informed of the dividend.

   f. Repurchase Agreements --The Portfolios may enter into repurchase
   agreements with commercial banks and with broker/dealers deemed to be
   creditworthy by J. & W. Seligman & Co. Incorporated (the "Manager").
   Securities purchased subject to repurchase agreements are deposited with the
   Portfolios' custodians and, pursuant to the terms of the repurchase
   agreements, must have an aggregate market value greater than or equal to the
   repurchase price, plus accrued interest, at all times. Procedures have been
   established to monitor, on a daily basis, the market value of the repurchase
   agreements' underlying securities to ensure the existence of the proper level
   of collateral.

   g. Expense Allocations -- Expenses directly attributable to each Portfolio
   are charged to such Portfolio, and expenses that are applicable to more than
   one Portfolio are allocated among them.

   h. Distributions to Shareholders -- The treatment for financial statement
   purposes of distributions made during the year from net investment income or
   net realized gains may differ from their ultimate treatment for federal
   income tax purposes. These differences primarily are caused by differences in
   the timing of the recognition of certain components of income, expense or
   capital gain and the recharacterization of foreign exchange gains or losses
   to either ordinary income or realized capital gain for federal income tax
   purposes. Where such differences are permanent in nature, they are
   reclassified in the components of net assets based on their ultimate
   characterization for federal income tax purposes. Any such reclassification
   will have no effect on net assets, results of operations, or net asset values
   per share of the Portfolios.

3. Purchases and Sales of Securities --Purchases and sales of portfolio
securities, excluding US Government obligations and short-term investments, for
the year ended December 31, 1999, were as follows:

      Portfolio                             Purchases              Sales
      --------                            -----------           -----------
      Bond                                $  2,752,375          $  2,716,199
      Capital                               35,890,837            42,495,567
      Common Stock                          20,079,705            37,108,873
      Communications and Information       163,592,271           180,811,782
      Frontier                              15,604,502            29,879,044

and $263,731 and $2,806,978, respectively, for the Income Portfolio.

   Identified cost of investments sold is used for both financial statement and
federal income tax purposes.

   At December 31, 1999, the cost of investments for federal income tax purposes
was substantially the same as the cost for financial reporting purposes. The tax
basis gross unrealized appreciation and depreciation of portfolio securities,
including the effects of foreign currency transactions, were as follows:

Manager pays the Subadviser a subadvisory fee for each of the Seligman
International Portfolios at a rate of 0.50% per annum of the average monthly

- -------------------------------------------------------------------------------

- -------------------------------------------------------------------------------

   On January 21, 2000, pursuant to authorization from the Fund's Board of
Directors, the Manager gave notice to the Subadviser of its termination,
effective as of the close of business on March 31, 2000, of the subadvisory
agreement between the Manager and the Subadviser in respect of Seligman Global
Growth Portfolio, Seligman Global Technology Portfolio, and Seligman
International Growth Portfolio (the "Global Portfolios"). During the notice
period, the Subadviser will continue to provide the Global Portfolios with
investment advice, research and assistance with respect to their non-US
investments, subject to the Manager's overall supervision. Following the close
of business on March 31, 2000, the Manager will assume full responsibility for
the non-US investments of the Global Portfolios. The Subadviser will continue to
act as subadviser with respect to Seligman Global Smaller Companies Portfolio.

   The Manager has agreed to reimburse expenses, other than the management fee,
that exceed 0.20% per annum of the average daily net assets of each of Bond,
Capital, Common Stock, Communications and Information, Frontier, High-Yield Bond
and Income Portfolios. The Manager, at its discretion and until it determines
otherwise, has elected to waive all of its fee for, and reimburse all of the
expenses of, the Cash Management Portfolio. The Manager has agreed to reimburse
expenses, other than the management fee, which exceed 0.40% per annum of the
average daily net assets of each of the Seligman International Portfolios. The
Manager, at its discretion, has also agreed to reimburse all expenses, other
than the management fees, of the Large-Cap Growth, Large-Cap Value and Small-Cap
Value Portfolios. The amounts of these reimbursements for the year ended
December 31, 1999 are disclosed in the Statements of Operations.

   Compensation of all officers of the Fund, all directors of the Fund who are
employees or consultants of the Manager, and all personnel of the Fund and the
Manager is paid by the Manager or by the Subadviser.

   Seligman Advisors, Inc., agent for the distribution of the CLVA-2 Contracts
and an affiliate of the Manager, received concessions of $155,856 from Canada
Life Insurance Company of America and $9,591 from Canada Life Insurance Company
of New York, after commissions paid to dealers for the sale of shares of the
Fund.

   Certain officers and directors of the Fund are officers or directors of the
Manager and the Distributor.

   The Fund has a compensation arrangement under which directors who receive
fees may elect to defer receiving such fees. Directors may elect to have their
deferred fees accrue interest or earn a return based on the performance of the
other funds in the Seligman Group of Investment Companies. The cost of such fees
and earnings accrued thereon is included in directors' fees and expenses, and
the accumulated balances thereof at December 31, 1999, are included in other
liabilities. Deferred fees and related accrued earnings are not deductible for
federal income tax purposes until such amounts are paid.

5. Capital Loss Carryforward -- At December 31, 1999, the Bond Portfolio,
Frontier Portfolio, High-Yield Bond Portfolio, and Large-Cap Growth Portfolio
had net capital loss carryforwards for federal income tax purposes of $212,775,
$428,834, $1,594,792, and $1,091, respectively, which are available for offset
against future taxable net capital gains. These net capital loss carryforwards
will expire in 2007. Accordingly, no capital gain distributions are expected to
be paid to shareholders until net capital gains have been realized in excess of
the available capital loss carryforwards.

6. Outstanding Forward Exchange Currency Contracts -- At December 31, 1999, the
Fund had outstanding forward exchange currency contracts to purchase or sell
foreign currencies as follows:

8. Committed Line of Credit --All of the Portfolios, except the Cash Management
Portfolio, are participants in a joint $750 million committed line of credit
that is shared by substantially all funds in the Seligman Group of Investment
Companies. Each Portfolio's borrowings are limited to 10% (5% for the Seligman
International Portfolios) of its net assets. Borrowings pursuant to the credit
facility are subject to interest at a rate equal to the overnight federal funds
rate plus 0.50%. Each Portfolio incurs a commitment fee of 0.08% per annum on
its share of the unused portion of the credit facility. The credit facility may
be drawn upon only for temporary purposes and is subject to certain other
customary restrictions. The credit facility commitment expires in June 2000, but
is renewable annually with the consent of the participating banks. For the year
ended December 31, 1999, none of the Portfolios had borrowed from the credit
facility.

9. Seligman Mutual Benefit Plan -- On December 31, 1998, MBLLife sold
substantially all of its general account life insurance and annuity businesses
to SunAmerica, Inc. The Order from the Superior Court of New Jersey (the
"Order") approving the transaction provided for the termination of the Mutual
Benefit Plan. The Order authorized MBL Life to take any and all actions
necessary to facilitate the termination of the Mutual Benefit Plan.
Contractholders were given the opportunity to exchange their contracts for
contracts issued by other insurance companies until June 30, 1999. At June 30,
1999, there were no remaining contracts.

Financial Highlights
- -------------------------------------------------------------------------------

   The tables below are intended to help you understand each Portfolio's
financial performance for the past five years or from its inception, if less
than five years. Certain information reflects financial results for a single
share that was held throughout the periods shown. Per share amounts are
calculated using average shares outstanding. "Total return" shows the rate that
you would have earned (or lost) on an investment in each Portfolio, assuming you
reinvested all your dividends and capital gain distributions. Total returns do
not reflect any administrative fees and asset based sales charges that are
associated with variable annuity contracts, and are not annualized for periods
of less than one year.

Report of the Independent Auditors
- -------------------------------------------------------------------------------

The Directors and Shareholders,
Seligman Portfolios, Inc.:

We have audited the accompanying statements of assets and liabilities, including
the portfolios of investments, of Seligman Portfolios, Inc. (comprising,
respectively, the Seligman Bond Portfolio, Seligman Capital Portfolio, Seligman
Cash Management Portfolio, Seligman Common Stock Portfolio, Seligman
Communications and Information Portfolio, Seligman Frontier Portfolio, Seligman
Global Growth Portfolio, Seligman Global Smaller Companies Portfolio, Seligman
Global Technology Portfolio, Seligman High-Yield Bond Portfolio, Seligman Income
Portfolio, Seligman International Growth Portfolio, Seligman Large-Cap Growth
Portfolio, Seligman Large-Cap Value Portfolio, and Seligman Small-Cap Value
Portfolio, collectively referred to as the "Fund") as of December 31, 1999, and
the related statements of operations, the statements of changes in net assets,
and the financial highlights for each of the periods indicated therein. These
financial statements and financial highlights are the responsibility of the
Fund's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements and financial highlights. Our procedures included
confirmation of securities owned as of December 31, 1999, by correspondence with
the custodians and brokers. An audit also includes assessing the accounting
principles used and significant estimates made by management, as well as
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of each
of the respective portfolios constituting Seligman Portfolios, Inc. at December
31, 1999, the results of their operations, the changes in their net assets, and
the financial highlights for each of the indicated periods, in conformity with
accounting principles generally accepted in the United States.
